+1... Given how much SSH is used for computer-to-computer communication it seems like there really should be a way to disable this when it isn't necessary.
In practice I've never felt this was an issue. But I can see how with extremely low bandwidth devices it might be, for instance LoRa over a 40 km link into some embedded device.
It looks like it is only applied for PTY sessions, which most computer-computer connections wouldn't be using.
